This white paper from JVD attempts to resolve several common misunderstandings about analogue and its role in an asic design. The paper discusses the need to consider full analogue design Vs the use of analogue library cells.

The 2nd generation Intel Core processor family brings huge improvements in processing power, graphics performance and power consumption. Further enhancements to power and a smaller footprint, make it the design-in replacement in 2011 for nearly all existing x86 platforms except for the Intel Atom class. But what is it exactly that makes the new processors so attractive?

Configuring a Phase Locked Loop (PLL) for a given frequency synthesis application can be, at the same time, both a quick and easy process as well as a time consuming, tedious, and iterative process. After determining a set of frequency synthesis parameters that meet the system needs, however, there is always the doubt: did I choose the best possible frequency synthesis parameters? Perhaps there is a different set that will run cleaner and consume less power or have more margin. It is these design choices that this article will attempt to shed some common sense design principles upon.

One of the first steps in embedded design is choosing a system architecture. Traditionally there have been two main options, symmetric multiprocessing (SMP) and asymmetric multiprocessing (ASMP). Today those two options are being combined using virtualization to form a new "soft ASMP" approach that offers many of the benefits of both SMP and ASMP. In this article we will look at the advantages of each approach and explain how Intel® Virtualization Technology (Intel ® VT) improves the performance of soft ASMP systems.

Networked devices such as digital signage, point-of-sale (POS) terminals, kiosks, and ATMs present unique challenges. A single enterprise may have hundreds or even thousands of these devices in locations around the globe. Managing these far-flung devices can be a difficult and expensive undertaking. Security is also a top concern for networked devices, which face threats from viruses, hackers, and other intrusions. These cost and security concerns can be addressed with Intel® Active Management Technology (Intel® AMT) and IEI's iEZman remote management software. These technologies help eliminate unnecessary tasks, reduce costs, and improve the security of networked devices.

Energy providers and governments worldwide are looking for ways to upgrade their energy systems. A big part of these efforts is the smart grid concept, which introduces networking and automation across the electrical system. The smart grid can give consumers and suppliers alike better monitoring and control of power consumption, leading to increased reliability, higher efficiency, and lower costs. However, computerization and connectivity bring with them the threat of security breaches and attacks.

Spectrum that was previously reserved for TV broadcasting is being freed up in many countries for use under the new Long Term Evolution (LTE) mobile radio standard. As a result, numerous coexistence scenarios are possible. So network operators and manufacturers from both the mobile radio and the broadcast sector have a vital interest in avoiding any interference and performing in-depth testing of their products. Rohde & Schwarz offers a wide ranging product portfoliIn many countries, spectrum that was previously reserved for TV broadcasting is being freed up for use under the new Long Term Evolution (LTE) mobile radio standard. Moreover, LTE will operate alongside broadcast applications in the future in this frequency range. As a result, numerous coexistence scenarios are possible. So network operators and manufacturers from both the mobile radio and the broadcast sector have a vital interest in avoiding any interference and performing in-depth testing of their products. Rohde & Schwarz offers a wide-ranging product portfolio for use in performing the applicable measurements on devices (e.g. interference immunity of user equipment, set-top boxes, etc.) and networks. for such applications.

The profusion of consumer devices with continuous connectivity, fluid graphics, and intuitive touch interfaces is raising expectations in automation arkets—including industrial automation, building automation, and home automation. These new expectations create difficult challenges for developers, who must implement the latest network and user interface innovations while minimizing cost and time to market. These development challenges are amplified by the fact that automation markets are highly fragmented, with each application presenting a unique set of requirements.

Ruggedisation and reliability are key requirements for a wide range of embedded computing markets, including industrial, medical, airplane or railway applications. Reliable operation is particularly important for safety-critical applications such as avionics and railway control. To meet the needs of these markets, embedded developers must carefully consider issues including hardware selection, manufacturing and testing methodologies, and software design. In this article we will explore these areas and show how embedded developers can build rugged systems with minimal cost and effort.

All digital oscilloscopes are temporarily blind. During this blind time the user will miss critical signal events at his device under test. Thus, it is necessary to understand the impact of blind time to the measurement. This application note explains the background of blind time and points out why a high acquisition rate is important. It furthermore explains the R&S RTO oscilloscope capabilities and how they help for faster debugging, measurement and analysis.

Communications networks are very different from other kinds of computing applications. Networks require both very high reliability and very high performance. Not only must they process large volumes of data at high speed, but they must do so while limiting their downtime to minutes per year. Network failures can have huge economic consequences and can even result in the loss of life. Additionally, in this post-9/11 world, failure also has a national security dimension. This technical whitepaper introduces MontaVista Linux Carrier Grade Edition — what it is, how it evolved, and how it provides a foundation for developing and deploying carrier-grade applications like those described above.

This whitepaper from Vector Fabrics describes the relationships and dependencies that exist, and will highlight them in the context of a new analysis tool called vfAnalyst that can be used to understand the behaviour of a program.

The demanding requirements put forth by redundant operation for both payload and management power can be met and interoperability between the power modules and the MicroTCA carrier hub achieved using MicroTCA compliant products.

The introduction of digitally controlled power supplies have huge impact on the Quality Assurance process and solutions to the issues discussed in this paper will be vital to the success of digital power in the telecom and datacom markets.

The concept of "digital power" has received significant attention and promotion in the past few years, from both semiconductor suppliers and power supply manufacturers. There is a need to explain the concepts of digital power; explore the advantages and tradeoffs of digital techniques compared to analogue approaches; discuss some of the standardisation directions; and explore the possibilities for digital power.

A tutorial for designers considering their first use of products based on the MicroTCA standard, and for the experienced designer looking for detailed information regarding optimal solutions for the power module design.

It is now several years since commercial products with 'added digital performance' aiming to revolutionise the power industry have been around in the marketplace. At a time when energy efficiency and power consumption are becoming more strategic than ever, the debate around how "digital power" will change the face of the world has never been so intense. Energised by the high marketing buzz surrounding 'the new power revolution', thousand of papers have often strongly expressed the details and benefits of implementing such technology. However, a certain market perception gives the feeling that behind the noise generated by the media, digital power seems not to have moved as fast as expected. Wrong perception or reality?

Digital control implemented in an isolated DC/DC converter provides equal or better performance compared to an analogue design. It also offers additional advantages in system energy management, improved flexibility and increased functionality.

It is now several years since commercial products with 'added digital performance' aiming to revolutionise the on-board power industry have been around in the marketplace. The debate around how such products will change the face of the world has never been so intense, resulting in a certain kind of confusion.
